PDFAbstract: Wireless communication system working over Gamma shadowed Nakagami-m multipath fading channel in the presence of cochannel interference exposed to Nakagami-m short term fading and Gamma long term fading is investigated in this work. In interference limited channel, the ratio of desired signal envelope and interference is important performance measure. For considered model signal to interference ratio can be calculated as the ratio of two products of square rooted Gamma random variable and Nakagami-m random variable. In this paper, the closed form expression for probability density function (
